Yehovah has His own calendar
We are now in the New moon - the 6th month – Elul, ΰΑμεΜμ
Neh.6  So the wall was finished in the twenty
and fifth day of the month Elul, ΰΑμεΜμ in fifty and two days
Neh.7 So the priests, and the Levites, and the porters, and the singers, and some of the people, and the Nethinims, and all Israel, dwelt in their cities; and when the seventh month came, the children of Israel were in their cities.
